To @ZZ whom t may concern,.-

Beit known that I, FRANK A. HOLLENBECK, a citizen of the United States,`residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Breech Loading Hammerless Guns; and I do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention is an improvement in haminerless breech loading fire arms and 'consists 1n the novel features hereinafter described, reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying my invention and the said invention is fully disclosed in the following description and claims.

This application is a division of my former application for Letters Patent of the United States filed by me July 25, 1892, and given Serial No. 441,209.

The object of my invention is to provide a construction for holding the cocking arms of the hammers in elevated position, in case the sears should release the hammers while the barrels are separated from the stock, thus en abling the barrels to Abe replaced in engagement with the stock, so that the cocking should ers, with which the barrels are provided, may be brought into operative relation with the cocking arms. To this end I provide a device which upon the removal of the barrels, will be moved into position to prevent the fall of the cocking arms, and upon reassembling the parts saiddevice will be engaged by a part connected with the barrels, and will be moved out of operative position to allow the cockin g arms to engage the cocking shoulders.

Referring to the drawings Figure lis a side elevation partly in section of a portion of a gun embodying my invention. Fig. 2 is a view similar to Fig. 1 showing the parts in dierent relative positions. Fig. 3 is an enlarged sectional View on line .fr-x of Fig. 2, showing in detail the device for securing the cocking arms of the hammers in elevated positions when the barrels are separated from the stock.

In the said drawings reference being had to the letters marked thereon, A represents the stock portion of the gun and B the barrels of ordinaryconstruction provided with the stock engaging lug b as usual.

The stock portion A is provided with a pivot pin or bolt a'which is engaged by lug b of the barrels and b is the fore end of ordinary construction. Y

The stock A is provided with a suitable lock casing in which is supported the pivot pin c vof the hammers C O Which are constructed preferably as shown. Iny the drawings each hammer isshown provided with the firing projection c', and the upper face or edge of each hammer is provided preferably with two locking notches c3, c4 which are engaged by the scar when the hammers are forced back- Ward into cocking position. Each hammer is provided with a forwardly extending cocking arm C which engages a recess b2 in the side of the lug b, and said lug is provided belowT said recesses b2 with solid portions b3 which I term cocking shoulders, which operatively engage the forward ends of the cocking arms C as clearly shown-in Figs. 1 and 2.

In order that the arms C may properly en.- gage the lugb and yet that thehammers may have their firing projections in line With the barrels, I prefer to locate the cocking arms C each upon the inside of its hammer O and in a different plane from the hammer and the two parts maybe formed in one piece or in two pieces suitably united. When the gun is broken and the barrels lowered, the cocking shoulders will operatively engage the under sides of the cocking arms and raise them, thereby depressing the hammers C C.

C2 is the main spring (there being one for each hammer), engaging a fixed pin or resistance at c5 and having its opposite end operatively combined with the hammer for actuat ing the same.

I) represents one of the sears, there being arm Which is engaged by one of the triggers E and a spring D engages the upper portion IOO of the sear and holds it in operative position. When the hammers are cooked by lowering the barrels as before stated, the soar will engage the first notch c3 of the hammer. Vhen however, it is desired to separate the barrel from the stock, the fore end will be removed and the barrels further depressed until the sear engages the second notch c4. In order to allow the barrel to be properly placed in engagement again with the stock so that the lug b will resume its operative relation with the cooking arms CC of the hammers, I provlde a construction for engaging the said cooking arm, when the barrel is removed from the stock andholding the same positively, thus preventing the hammer from being dropped even should the triggers be intentionally or accidentally moved to release the sears.

In the forward part of the frame a pawl or catch is pivoted, the said pawl consisting of a vertical stem F having its upper end provided with laterally extending arms ff, best seen in Fig. 3. This pawl is pivoted in the lower 'part of the frame in a suitable recess and has a forwardly extending nose or projeotion f', see Figs. 2 and 3, which projects into the recess a of the frame, when the barrel lug is removed therefrom and engages a solid portion of the lug b intermediate the recesses b2 when the lug is in operative position in said recess a as indicated in Fig. l. The nose f' of the pawl has a curved or beveled face fx'which I term a cam face, for engaging the barrel lugwhen the parts are assembled or I may provide the lower corner of the lug with a cam face to engage said nose yif preferred. In rear of the stem F of the pawl the frame is providedwith a recess in which is located a spring f2 which engages and presses the pawl forward.

Each cooking arm C is provided on its inner side with a projection or lug cX as shown in Figs. 2 and 3 5 the said lugs or projections being so located that when the cooking arms are raised above thelaterally extending arms f f of the pawl and the pawl is thrown forward by its spring f2, the said arms ff will be moved beneath the lugs cX oX of the cooking arms and will hold them in an. elevated position.

In Fig. 1 I have shown the position of the parts as they would appear when the gun is broken to load. It will be seen that the cocking arms are raised by the oockin g shoulders b3 of the lug b and the hammers are cocked and held in cocked position by the scar engaging the notches o3 of the hammers. In this position the lugb will prevent the spring actuated pawl from moving forward and the arms f f of -said pawl will therefore not engage the lugs o c of the cooking arm.

c2 represents the position of the parts when the fore end is removed and the barrels are further depressed prior to removing them when in engagement with the stock. The sear in this case will engage the second notch c4 of the hammer and as soon as the lug b has moved far enough to disengage the nose f of the spring actuated pawl said pawl will be thrown forward by its spring bringing the arms ff beneath the lugs c cX of the cooking arms and positively preventing the cooking arms from descending. It is obvious that I may dispense with the second notch c4 in each of the hammers as the spring actuated pawl will in any 'case positively prevent the falling of the cooking arms, while the barrffnls are removed from engagement with the stock.

In assembling the parts of the gun, the lug is placed in engagement with the pivot a and theouter end of thefbarrel will be raised, thereby causing the lower edge of the lug to engage the cam face of the spring actuated retaining pawl and pressing i-t inward thus allowing the cooking shoulders to pass beneath the cooking arms before the cooking arms are permitted to fall thus placing the parts in operative relation again. It will thus be seen that the spring actuated pawl constitutes 'an automatic retaining device which insures the parts being properly assembled after the barrels have been removed from the stock.

I do not desire to be limited to the exact details'of construction herein shown and described as variations may be made therein withoutdeparting from the spirit of my inl vention. A

What I claim, and. desire to secure by Letters Patent, is-

1. In a fire arm, the combination with th r barrels having the cooking shoulders, of the hammers provided with cooking arms, and the spring pawl for preventing the fall of said arms, having a part engaging a part oonnected with the barrels and holding the spring pawl out of operative relation with said arms when the parts of the gun are assembled, substantially as described. v

2. In a lire arm the combination with the barrels provided with cooking shoulders, of the hammers and their cooking arms and the spring pawl having parts engaging the oooking arms when the parts of the gun are separated and a part engaging the barrel lug and holding said pawl out of operative position when the parts of the gun are assembled, substantially as described.

3. In a tire arm the combination with the barrels having a lug provided with cooking shoulders, of the hammers, the cooking arms adapted to be engaged by said shoulders, the spring actuated pawl having a cam portion adapted to engage the barrel lug and portions adapted to support said cooking arms, when the lug is moved out of engagement with said cam portion, substantially as described.

et. In a re arm the combination with the barrels having the cooking shoulders, of the hammers and their cooking arms and a movable device for holding the cooking arms in position to permit the removal and return of the barrels, said device having a part engaging a part connected with the barrels and IOO IIO
